Specification of Letters Patent.

Patented June 25, 1907'.

Application filed November 24, 1906. Serial No- 344,892.

To all whom, it may concern:

Be it known that I, ALFRED WALTHo, a subject of the King of Great Britain and Ireland, residing at 17 Earlston road, Liscard, in the county of Chester, England, have invented a new and useful Improvement in Bottle-Stoppers, Electrical Fittings, and the Like, of which the following is a specification.

My invention relates to an improved machine for molding bottle stoppers, electrical fittings, such as cut-outs, ceiling roses, and the like, and it is especially applicable to the outside or contour of the stoppers which are molded so as to bear or be formed to represent a letter of the alphabet or it may be some other symbol, for instance a horse shoe, a star or other shape.

The invention will be best understood by referring to the accompanying drawings in which:Figure 1 is a side elevation of the entire machine. Fig. 2 is a sectional plan on line c a: of Fig. 1. Fig. 3 is a section on line yy of Fig. 1. Fig. 4 is a side elevation partly in section of a portion of Fig. 1. Fig. 5 is an enlarged view showing portions of Fig. 4 on an enlarged scale. Fig. 6 is a side elevation of parts of Fig. 1 on an enlarged scale. Fig. 7 is a plan of Fig. 6. Fig. 8 is a detail view of the compound plunger hereinafter described. Fig. 9 is a sectional view of a modified method of ejecting the article after molding. Fig. 10 is a plan of one of the products of my machine to be hereinafter described, and Fig. 11 an inverted plan of the same.

Parts are omitted from some of the figures for the sake of clearness.

Similar letters refer to similar parts throughout the several views.

1 is a table which is revolved step by step by means of one or more handles 2, and 3 is a rigid fixed race to support and guide the table 1.

trays 7 and said trays are removably mounted in the revoluble table 1 (see Figs. 2 and 6.)

8 are flanges on the molds to prevent them dropping through the trays 7 and 9 are flanges on the trays to prevent the latter dropping through'the table 1. .The compound plungers (there being six in this case) comprise a central spindle 11 and a sleeve 12 surrounding it. For molding articles this sleeve has at its lower end a series (in the example shown three) of slots 13 and these slots are widened out below as shown.

-The spindle 11 carries three lugs 14 and when the spindle and sleeve are closed up together they form a solid core or compound plunger having three depressions 15- in its side. In operation, as soon as these slots reach the lugs 14 they intermesh and spindle 11 is also carried down and the compound plunger is pressed down into the mold thus spreading the composition and forcing some of it to enter the slots to form the lugs on the inside of the cap. The sleeves are then raised so much as to cause slots 13 to rise just above the lugs. The spindle is then turned which causes said lugs to assume a position immediately below the solid parts of the sleeve. There is thus a free way open for withdrawing the compound plunger without disturbing the formed lugs. 16 is a'carrying plate to which the sleeves 12 are fixed. These plungers are synchronously moved by one handle 17 connected to said plungers by a frame 18 and links 19. A spring 19 surrounding the shank of the handle 17 tends constantly to force it outward and to therefore replace the revoluble plungers into their normal position. until they are again turned ready for a descent on to and into the clay or other plastic mass in the molds.

20 are collars or lids on the plungers such collars being kept down by springs 21 and guided by rods 22 so that when the stroke is made they rest on the top of the molds while at the same time after they have reached their position a further depression of the lever 5 causes the plungers to be pushed right home. I prefer also to provide a catch plate 23 (see Figs. 1, 2, 3, and 4) which rides idlethat is to say it drops down on top of the plungers being guided by pins 24. When this catch plate descends it passes a catch 25 which immediately springs back again into place so as to prevent the complete upward return movement of said catch plate until on the stem of handle 17 serves to knock away the catch and to allow all the parts to return to their normal position.

In the modification shown in Fig. 9, I dispense with loose molds or linings and substitute therefor false or loose bottoms 27 having depending rods 28 surrounded by springs 29.

30 is a plate supported on the end of a rod 31 which 18 operated by a treadle or lever 32 so that when such lever is depressed the rising of the plate pushes up the false bottoms thereby ejecting the articles from the mold the bottoms being returned to their normal positions by the springs on release of the treadle in obvious manner.

Referring to Figs. and 11 which shows one of the products of my machine formed to represent the letter G. 33 is the body of a stopper and 34 internal projections formed as before described.

That I do claim as my invention and desire to secure by Letters Patent in the United States, is

1. The combination of a table having an intermittent rotary motion and carrying a set or series of molds, with a set or series of plungers each of which consists of a central spindle and a sleeve surrounding it such spindle being rotatable and vertically movable within such sleeve which is provided with slots the lower portion of which are adapted to receive lugs carried by the spindle substantially as and for the purposes described.

2. The combination of a mold carrying table and plungers adapted to enter such molds, with a frame having links connected to such plungers and a spring actuated handle whereby the set of plungers are synchronously moved substantially as set forth.

3. The combination of a table 1 compound plungers 11 and the means for operating them, with a catch device consisting of plate 23 catch rod 17 and collar 26, substantially as set forth.

1. The combination of table 1 and the means for fixing it in any desired position, compound plungers 11, sleeves 12, springs 21, collars 20, frame 16, links 19, handle 17 catch plate 23, catch 25, rod 17, and collar 26, all operating in the manner and for the purposes herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALFRED WALTHO.
